PASSENGER-CAR VENTILATION.

SPECIFICATION forming part of Letters Patent No. 249,533, dated November15, 1881.

Application filed August 17, 1881. (No model.)

To all tchom itmay concern:

Be it known that I, THDMAS P. KINSEY, of

the city of Reading, county of Berks, State of Pennsylvania,haveinvented certain newand useful Improvements in Passenger-CarVentilation, of which the following is a specification.

This invention is an improvement upon the Patent No. 238,777, March15,1881, Fox and Kinsey, and is more particularly intended to obviatesome objections to said patent occasioned by the encroachment on theclearing space between the tracks (on double-track lines) by theadditional width given the pasin section above.

senger cars over the original standard. For single-track or wideclearance roads there is no occasion to deviate from the previousdevices.

The accompanying drawings form a part of this specification, andrepresent what I consider the best means of attaining the desiredresult.

Similar letters represent similar parts.

Figure 1 isa sectional view of the interior of a passenger-car from thefloor to lower edge of the monitor top, the latter being removed, andthe air-receiving box shown detached and Fig. 2 is a partial front andcross sectional elevation of a passenger car. Fig. 3 is a detail view ofthe air-ducts. Fig; 4 is a detail view of the air-distributors.

A represents the car; B, the air-receiving box, of which there aretwo,'placed oneon each side of the monitor top upon the roof of the car.Preferably they will be madeof zinc or tin, in size of oblong sectionsix by eight inches, and extend the entire length of the carroof, andprovided with enlarged cone heads B ateither end, covered with a .coarsewirescreen, 0. Back of the cone at the entrance to r B is placed a finewire screen, I).

On the lower side of the cone, and between the wire-screens O D. is anopening, D, and back of the screens D, in the pipe or box B, are placedautomaticflap-valves E E suspended from a cap, F, fastened on top of thebox B.

At points in the length of the air-receiver B,

indicated by the number of air-ducts affixed to that side upon theinterior of the car, are branch pipes H H, connecting the air-ducts andthepi-pe B. Immediately over said'branch 'erated from the exteriorof thecar.

' pipes are openings f, left in the cover of the box, which are closedby caps upon the under side of which are secured deflectors g g,projecting the requisite distance in the box to deflect a certainportion of the entering air into and down the connecting-pipes H H.

J represents the improved air-ducts, which may be of cast-iron orstamped out of zinc or tin. Fig. 1 gives their general appearance in thecar, while Fig. 3 shows more clearly their construction. Agoodworkingsize would be about two feet long, eight inches wide, and fourinches deep. A partition, K, starts from one side of theopening of pipeE into J, and is carried nearly across at a tangent to the registeropening in the cap, makes a semicircle around the lower edge of theopening and a perpendicular rise to the height of the diameter of thesame. The register opening J in the cap of the air duct is provided withthe usual register-wheel, and is covered over by the air-distributorcase L. A stein cast with or secured in the register-wheel projectsthrough the front of the distributor case, and has a pointer on the end,so arranged with reference to markings on the case as toindicate theopenin g or closing of the air-duct register. Underneath, at the base ofthe air-duct case, is a boss,

Jlll, d d for gas-pipe, by which it is (3011- nected with the system offilling and discharge orflushing pipes O and P. These pipes arecontrolled on both sides of the car by stopcocks R, placed at each endof and within the car, being so arranged that they may be op- At eachend of and on the-outside of the car are placed stand or gage pipes S,so adjusted that when the water in filling of the air-duct reservoirsreaches the proper height it will be indicated by the flow ofwater fromthe pipes S.

To get the fillingand discharging apparatus out of the way of theentrance to the cars, I use a return-bend, short length of pipe, elbowS, and hose-coupling T, which brings the ap paratus at theside of thecar (outside) and within reach of the stop-cock communicating with theducts inside of the car. The stopcock, as is usual with cocks designedto cut. off back of an open pipe, will have an air-hole so out of zincor tin, and so constructed that the discharge-mouth M shall project theair upward and outward in curves from the distributors toward the centerand sides of the car.

- Nos.1 and 2 in Fig. 1 show the air-distributers as arranged for theordinary parlor-car, while Nos. 3 and 4, Fig. 1, show them as arrangedfor distributers in a sleeper.

In operation the car, supposed to be running to the left, the flap-valveIt at the advancing end of the pipe B will open, while that at the rearend will close against the fine screen D. Air will now enter with moreor less iorre, governed by the speed of the car, the larger cindersbeing stripped therefrom by the screen O,'and those that pass through 0bein gin tercepted by D will drop out of the opening D, provided forthat purpose between the two screens. The air, freed from cinder butcarrying more or less dust along, will fill up the box B, and throughthe operation of the deflectors g g, assisted by the reduction ofpressure in the car from the exhaustion of the same by the fan, (asdescribed in Patent No. 238,777, March 15, 188l,'Fox and Kinsey,) willpass down the connecting-pipes H, be deflected by the partition K downupon the water in the reservoir,where it will be freed from dust, andrising over the rear of the partition pass through the'air-duct registerand out of the air-distribnters into the car.

The sectional area of the pipes H and the clear opening of theair-registers are governed by the number of air-ducts placed at the sideof the car, and to be supplied by the air-receiving pipe '13. Dividingthe area of B by the number of air-ducts will give the area of H and J.This mode of furnishing fresh air forventilation is notconfined to carsexhausted by'a fan, but is applicable to all cars where a current of airis discharged from a car in any manner whatever.

I am aware that air receiving and discharging boxes on passenger andother cars are not new, that a box of that character having flapsautomatically operated to open said pipe in the direction of theadvancing car and closing the opposite end are also not new, (see PatentNo. 171,611, December 28, 1875, G. F. Godley; No. 186,251, January 16,1877, J. B. Hill; and No. 11,494, August 8, 1854, Reed and Mould,carventilators ;)'but I believe myself to be the first to so construct,arrange, and combine the same as to furnish a complete system offreshair supply, in combination with the discharge of foul and heatedair bythe exhaustion of the What I claim, and desire to secure byLetters Patent, is as follows, to ,wit:

1. In combination with a passenger or other car, and placed on the roofof the same, an airreceiving box, B, preferably of oblong section,extending longitudinally from end to end of the car-roof, provided ateach end with enlargedheads B, the opening being covered with coarsewire O to exclude large cinders, a similar screen, D, of finer meshplaced at the entrance of the box proper and between the two screens,the opening D, for the discharge of cinders passing the screen 0,substantially as shown, and for the purpose described.

2. An air-receiving box, B, provided with openings fon its top andopenings h beneath, the openin gs f bein gclosed with caps F, havingsecured to their inside face deflectorsg, so arranged with relation tothe openings h as to deflect a certain portion of air through the same,in combination with the connecting-pipes H and air-ducts J on theinterior of the car, substantially as described, and for the purposespecified.

3. An air-duct reservoir or box, J, provided with adeflecting-partition, K, constructed as described, having aregister-opening, J, upon its face, controlled by the usualregister-wheel plate, a water-reservoir, J, and a boss, J', combinedwith the air-receiving pipes H and B above it, with the water-pipes andcock 0, P, and R below it, and with the air distributer L throughspindle and pointer N, as described,

and for the purpose set forth.

4. The combination of supply and discharge pipes O and P, stand-pipes S,return-bends S, and hose-couplings T, with the air-duct boxes J on theinterior of a passenger or other car, arranged and constructed to becontrolled in their operation by cocks R, placed at each end of andinside the car, said cock being adapted to be operated from the outsideof the car, substantially as shown, and for the purpose described.

5. The automatic flap-valves E, provided at each end of the air-box B,and in combination therewith, arranged to be removed and replacedthrough an oblong cross-slot in the top of the box B, said slot beingcovered by thecap F, to which the flap-valve is hung, substantially asshown and described.

6. The combination of the air-ducts J, with 'the air-distributers L, theback of the latter THOMAS P. KINSEY.
